Product details

TransZorb Zener TVS — 300V rail clamp for DC bus and industrial supply protection

The 1.5KE350A-E3/54: Its 300 V reverse standoff voltage and 482 V clamping maximum make it a fit for protecting 300 V DC bus rails, industrial power supplies, and telecom rectifier outputs against transient overvoltage events.

Clamping performance and pulse current handling

With a breakdown voltage range starting at 333 V minimum and a clamping ceiling of 482 V at 3.1 A peak pulse current, this diode absorbs transients that would otherwise stress downstream semiconductors.

Package and board-level integration

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE350A-/54 is a through-hole part suited for point-to-point wiring or PCB mounting with lead bending. The 1.5KE supplier device package footprint matches standard TVS axial layouts, and the part is available in tape-and-reel or cut-tape options for batch assembly or prototype runs.
